Crook: [during a diner robbery] What’s you doing, you pighead sucka?
Harry Callahan: Every day for the past ten years, Loretta there’s been giving me a large black coffee. Today she gives me a large black coffee, only it has sugar in it, a lotta sugar. I just came back to complain. Now, you boys put those guns down.
Crook: Say what?
Harry Callahan: Well, we’re not just gonna let you walk out of here.
Crook: Who’se we sucka?
Harry Callahan: [slowly drawing his .44 Magnum] Smith and Wesson... and me.
Classic Dirty Harry scene.
